Description
Technical Field
The present invention relates to a method, a communication device, an unmanned aerial vehicle, a computer program and a computer program product thereof for enabling autonomous emergency assistance for one or more communication devices registered in a conventional cellular network.
Background
Unmanned Aerial Vehicles (UAVs) are used throughout society in a wide variety of applications. Examples include delivery services, aerial photography and film production, remote sensing tasks for agriculture, city planning, civil engineering, support for public safety and rescue services, etc. There are many different types of UAVs that can be remotely controlled using Wi-Fi or some proprietary radio technology. UAVs are capable of communication, sensing, and autonomous operation, and are also capable of analyzing data collected via sensors, cameras, and the like. UAVs may be used as relays between ground-based terminals and network base stations to extend the reach of the network (reachrange). Furthermore, the UAV may act as a flying GSM base station and then provide cellular network coverage to the user [ UAV-based GSM network for public safety communications, IEEE, K Guevara, 2015 ].
Robust network access is crucial for safe and efficient rescue operations in disaster areas and in connection with emergency situations. It is possible to set up a mobile network for voice and data communication that enables the assistance mechanism to work more efficiently at the disaster site. This may be done, for example, using a satellite dish (satellite dish) and a Wi-Fi access point. Furthermore, the Ericsson Response MiniGSM system is an overall system solution comprising different functional components, such as Mobile Switching Centers (MSC), Base Station Controllers (BSC), Radio Base Stations (RBS), network management, network databases and operation and maintenance (O & M). The unit was built into a 7 foot long container that was easily transported to accomplish climate control of the equipment. System maintenance and operation may be managed locally or remotely. The system supports GSM 900, 1800 and 1900 MHz frequencies, either single or dual band. The network can operate independently with its own network identity or it can be part of a larger network. In both cases, subscribers from other networks may roam to the MiniGSM system under the same conditions as for any other cellular network. Coverage areas with radii up to 35 km can be established.
All of these digital assistants have in common that they rely on internet access (i.e., cloud-based) and on Artificial Intelligence (AI) technologies called deep learning (and natural language processing (N L P)), which requires access to a large amount of data to give software the ability to do things like understanding human speech.
The 3 rd generation partnership project (3 GPP) Technical Specification (TS) 36.331, sections 5.2.1.1 and 5.2.1.2 describe how to handle system information within, for example, a long term evolution (L TE) system.
The system information is divided in L TE into MasterInformationBlock (MIB) and several SystemInformationBlock (SIB) MIBs including a limited number of most basic and frequently transmitted parameters required to acquire other information from the cell, the MIBs being transmitted on a Broadcast Channel (BCH). SIBs other than SystemInformationBlock type1 are carried in SystemInformationBlockType1 and the mapping of SIBs to SI messages is flexibly configurable by schedulingInfo L included in SystemInformationBlockType1, with the restriction that each SIB is only contained in a single SI message and appears at most once in the message.
For a Time Division Duplex (TDD)/Frequency Division Duplex (FDD) system with a bandwidth greater than 1.4 MHz supporting bandwidth reduction complexity (B L) User Equipment (UE) or UE in Coverage Enhancement (CE), MIB transmissions may be repeated in subframe #9 of a previous radio frame for FDD and MIB transmissions may be repeated in subframe # 5 of the same radio frame for TDD.
MIB Multimedia Broadcast Multicast Service (MBMS) uses a fixed schedule with a 160 ms periodicity and repetition within 160 ms. The first transmission of MIB-MBMS is scheduled in subframe #0 of the radio frame SFN mod 16 = 0 and repeatedly scheduled in subframe #0 of all other radio frames SFN mod 4 = 0.
The systemlnformationblocktype 1 uses a fixed schedule having a period of 80 ms and repeating within 80 ms. The first transmission of the systemlnformationblocktype 1 is scheduled in subframe # 5 of the radio frame of SFN mod 8 = 0 and repeatedly scheduled in subframe # 5 of all other radio frames of SFN mod 2= 0.
The MIB is the first thing the UE looks for after it achieves downlink synchronization. The MIB carries the most basic information that the UE needs to be able to obtain other information from the cell, including:
● Downlink channel Bandwidth
● physical hybrid automatic repeat request indicator channel (PHICH) configuration
● SFN, i.e. System frame number
● evolved node B (eNB) transmit antenna configuration specifying the number of eNB Transmit (TX) antennas
The SIB1 is carried in the systemlnformationblocktype 1 message. It includes information about UE cell access and defines the scheduling of other SIBs, such as:
● public land Mobile network (P L MN) identity
● Tracking Area Code (TAC) and cell ID
● cell barred state (whether the UE can camp on a cell)
● q-Rx L evMin, minimum received (Rx) level required in a cell to meet cell selection criteria
● Transmission time and periodicity of other SIBs
The SIB2 contains common radio resource configuration information for all UEs, including:
● uplink (U L) carrier frequency and U L channel bandwidth
● Random Access Channel (RACH) configuration, i.e., preamble information, transmit time in frames and subframe numbers (physical RACH-ConfigInfo), and powerRampingParameters
● paging configuration, paging cycle
● U L Power control configuration, P0-NominalPUSCH/Physical Uplink Control Channel (PUCCH)
● sounding reference signal configuration
● PUCCH configuration for transmission of Acknowledgement (ACK)/non-ACK (NACK), scheduling request, and Channel Quality Indicator (CQI) reporting
● PUSCH configuration
The SIB3 contains common information for intra-frequency, inter-frequency, and/or inter-Radio Access Technology (RAT) cell reselection (information does not necessarily apply to all scenarios, see 3GPP TS 36.304 for details).
The SIB4 contains intra-frequency neighbor cell information for the L intra-frequency cell reselection, such as a neighbor cell list, a cell blacklist, and a Physical Cell Identity (PCI) of a Closed Subscriber Group (CSG).
The SIB5 contains neighbor cell related information for inter-frequency cell reselection within L TE, such as neighbor cell list, carrier frequency, cell reselection priority, thresholds used by the UE in reselecting frequencies with higher/lower priority than the current serving frequency, and so on.
The SIB6 contains information for inter-RAT (IRAT) cell reselection to Universal Terrestrial Radio Access Network (UTRAN), such as:
● list of carrier frequencies: list of adjacent UTRAN carrier frequencies
● cell reselection priority: absolute priority
● Q _ Rx L evMin minimum Rx level required
● ThreshX-high/ThreshX-low: threshold used by UE in reselecting higher/lower priority frequencies than the current serving frequency
● T-Reselection URTA: cell reselection timer value for UTRAN
● speed dependent reselection parameters
The SIB7 contains information for IRAT cell reselection to GSM/EDGE radio access network (GERAN) (similar to SIB 6).
SIB8 contains information for IRAT cell reselection to evolved high rate packet data (eHRPD), which is 1xEV-DO rev.a supporting connectivity to the evolved packet core of L TE.
The SIB9 contains the home eNB name, where the home eNB is a femto cell in the context of L TE, a small base station in a residential area, or used by a small enterprise.
SIB10 is used for Earthquake and Tsunami Warning System (ETWS) primary notification. The paging procedure is used to inform ETWS-capable UEs in Radio Resource Control (RRC) idle and RRC connected modes to listen to SIB10 and SIB 11.

The field description:
US2016/0127439 describes how a UE receives a system information broadcast message containing a multimedia alert therein. The multimedia alert triggers the UE to automatically launch a multimedia broadcast application to process the alert, thereby automatically tuning the UE to the streaming multimedia content associated with the alert and enabling processing of the streaming multimedia content at the UE.
The UE is not required to respond to the network with an alert contained in the system information broadcast. The network does not receive any data from the UE.
US2016/0360562 discusses an autonomous Unmanned Vehicle (UV) that may include a UAV operable as a mobile node (UV node) in, for example, a mesh network, providing network access to a terminal in a remote location. Terminals that are considered to be UV-friendly may access the network via UV. It is described how to preset commands for specific tasks performed by the terminal after reception from the UV node (which may be similar to setting up a dialog).
Only known/friendly devices can access the network provided by the UV.
US2016191142 discloses a method for improving cellular coverage of an existing (and operable) cellular network by providing a UAV to a priority zone so that the UAV may operate as a temporary mobile device cellular tower. The document seems to focus on how to find areas that would be critical with respect to coverage or accessibility.
The method does not detect and initiate a conversation with people and devices in an emergency situation.
US2016337027 discloses a method for detecting a UAV by a ground terminal and setting up a connection to a network via the UAV by directing an antenna beam towards the UAV. According to paragraph [0037], a ground terminal can be, for example, a mobile terminal. That is, a method for a ground station to detect and connect to a UAV is described.
These documents disclose the establishment of temporary connections as both an alternative and a way to increase capacity. Predetermined commands may be provided from the UAV to the terminal for completing certain tasks, and sensors may be used to collect data. The terminal may find a UAV, and the UAV may search for the terminal.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the description.
Today, it is a problem to automatically obtain and analyze important information from people and devices in an emergency area, without or very limited network access.
Today's solutions use cell broadcasting for emergency alerts (earthquake and tsunami warning system (ETWS), Commercial Mobile Alert System (CMAS) to Communication Devices (CDs) within range of the base station, but do not enable CDs to automatically respond to such alerts/pages.
In case of a large emergency or disaster situation, in case of no or limited network access, existing solutions have e.g. the following problems:
● initiate access to CDs in emergency/disaster areas.
● trigger the automatic collection of data from the CDs of the emergency/disaster areas.
● enable data collection and analysis from CDs in emergency/disaster areas or near network edges.
● determining the number of CDs (known and otherwise) in a portion of the emergency area
● enable the network edge (near the network edge) to initiate a conversation with a CD in the emergency/disaster area.
As proposed herein, this is enabled with Unmanned Aerial Vehicles (UAVs) and CDs, where UAVs simulate base stations in a cellular network, and CDs are able to connect to the cellular network. The UAV may send broadcast emergency response triggers to CDs within range, including information about how to respond and what data to utilize. The CD receives an emergency response trigger from the UAV, connects to the UAV using access information included in the emergency response trigger, and transmits a CD emergency response including the requested data. The request for response data may, for example, request that the response should indicate a received counter value, CD ID, location, battery status, and/or emergency status.
The following examples are proposed: for CDs within the UAV range as described herein, connectivity is provided, emergency information is provided, and collection of data from CDs and users within range is triggered. Data obtained from CDs within range can be continuously analyzed to provide an overview of the condition and support the person in need.
The use of autonomous emergency assistance for disaster areas is described below. This functionality is implemented in the CD (as a downloaded application, or built-in functionality):
1) an area is struck by an earthquake and the moving network is destroyed.
2) An autonomous UAV is guided into a disaster area. UAVs contain devices that simulate cellular networks.
3) Several CDs discover new networks and receive System Information Blocks (SIBs) from the UAVs, which include emergency response triggers and emergency information, including predefined information about earthquakes and evacuation information, for example.
4) Each CD may signal the user, for example, by displaying emergency information on a screen or by playing a voice message, and if privacy settings allow, the CD may be automatically connected to the UAV and send a CD emergency response with the requested data (such as location data). The CD may respond with information, for example, if the user has been signaled but not responded, which may indicate that the user is in urgent need.
5) In addition to automatic responses, the user may also respond manually and communicate with the UAV, for example using voice or text messages.
6) The UAV may respond to any manual communications using text messages or speech synthesis as a chat robot (chatbot). The user may notify the UAV of the emergency state, and the UAV may give further instructions.
7) The UAV analyzes data collected through automatic CD emergency responses and optional manual communications and takes appropriate actions, such as:
a. communication is initiated with a user who has not manually replied to.
b. An emergency center or area with network coverage is immediately returned to forward the information retrieved from the one or more CDs to the emergency center.
c. Proceed to disaster areas or other areas to gather more information.
The embodiment shown in fig. 1 includes the following components:
● UAV 2, which:
○ simulating a cellular (emergency) network
○ System Information Blocks (SIBs) for emergency information are transmitted to the CD, which SIBs trigger responses from the CD and optionally from its users
○ collect and analyze data from CD within range
○ take appropriate action(s) based on input from the CD, sensor input, and UAV data
● have cellular subscribed CD(s) 1 such as User Equipment (UE), smart phones and sensors, and internet of things (IoT) devices, which
○ receive system information and respond automatically (e.g., by downloaded applications) based on the received information
● center of operation 3
○ is responsible for controlling UAVs
Connectivity between the UAV and the CD may be enabled by the following steps, as shown in fig. 2:
1. UAV 2 enters an area and simulates a cellular network, broadcasting a signal tells all CDs 1 within range that there is now a cellular network available for communication.
2. CD 1 within range discovers the cellular network by cell searching and selecting UAV 2 as a base station for the discovered cellular network.
3. UAV 2 broadcasts emergency information to CDs within range using auxiliary SIBs and/or existing standard SIBs 10/SIB11 to trigger CD automatic responses and to inform them how to respond.
4. The CD 1 receives system information through an SIB including the authentication _ response _ trigger. Emergency information may be provided to the CD and displayed, for example, on the CD or played in a voice message, and an automatic CD response is prepared via, for example, a downloaded application. The SIB contains at least a bit indicating whether an automatic or manual user response is required.
5. UAV 2 and CD 1 continue with the random access procedure, wherein the CD transmits response information related to the random access procedure. An alternative is to include an automatic CD _ authentication _ response in the response message in the RACH procedure, e.g. in so-called message 3, which otherwise follows the standard RACH response. In another alternative, an automatic CD _ authentication _ response is included after the RACH procedure, where the connection has been set up and data is allowed to be sent. The UAV collects the received CD data and may, for example, determine the number of CDs within range and their status, and may also decide to take appropriate action directly as set forth in point 7 without collecting further information by further communication with the CDs set forth in point 6. The UAV may, for example, determine and store a number of known CDs, i.e., CDs pre-registered in the UAV, such as the CD of a rescuer located within range of the UAV, and other previously unknown CDs within range of the area or portion of the area (such as a sector of the area), and sum the number of CDs in different sectors of the area. In this way, previously unknown CDs become known to the UAV during the random access procedure.
6. After the random access procedure, for example, depending on an earlier response, the UAV may request further information of CD 1, which may be a continuation of the already established contact, or may request by transmitting a further mergency _ response _ trigger. CD 1 responds automatically and/or manually in further communication with the UAV. Thus, the further received emergency _ response _ trigger may be an emergency _ response _ trigger other than the emergency _ response _ trigger received in point 4. The further response may include an automatic CD _ occurrence _ response or an additional _ occurrence _ communication or a combination of both that allow user input. The selection of what the response should include may be indicated by a trigger received in the further request.
7. The UAV 2 collects and analyzes all CD responses and takes appropriate action, such as providing data to the operations center 3 (by flying back to the operations center), notifying possible rescue personnel within range, or providing advice to the user, such as moving to a safe area, for example as shown by a map. The indication to the security zones may be sent separately to a particular CD having detailed instructions on how to reach the security zones, or may be broadcast with general information on where one or more security zones may be found.
Connectivity between the UAV and the CD, here exemplified by a User Equipment (UE), may be enabled by the following sequence, as shown in fig. 3.
1. The UE is in idle mode and searches for a cellular network. The UE finds an emergency network provided via the UAV ("red cross" network), and receives system information from the UAV.
2. The UAV may send a paging message with the ETWS notification to the UE, informing the UE of the emergency to monitor.
3. The UE is now ready to receive the SIB containing the Emergency _ response _ trigger.
4. The UAV may send a primary notification SIB10, such as, for example, "earthquake," and optionally, a secondary notification SIB11, such as, for example, "warning message," including emergency _ response _ trigger.
5. The UAV may send response triggering auxiliary SIBs, including emergency _ response _ trigger, which may also indicate the type of response data requested, alarm type, counter, trigger. The auxiliary SIBs may be used outside of the general paging message (Point 2) and/or outside of the SIB10/11 message (Point 4), or may be used without the previous messages 2 and 4.
6. The UE decodes the received information and may present the received information to the user. The received information may be presented to the user by text on a display or by audio in a voice message.
7. The UE decodes the received trigger and prepares a response. The received trigger may, for example, request an automatic response, a manual response, or a combination of both.
8. In a Random Access Procedure (RAP), the UE transmits an automatic response message indicating, for example, a CD _ ID, a counter, data such as a location, a battery status, and an emergency status in a RACH procedure.
9. The UAV collects the received UE data, analyzes them, and may determine, for example, the number of UEs within range, and thereafter determine the condition.
10. After the initial access procedure, the UAV may request further information, such as through http or SMS communications. The request for further information may for example depend on earlier received responses. Further information may, for example, ask for a user response, such as whether there are other people in distress.
11. The UE receives a request for additional emergency communications including, for example, a source, an alert type, and text. The source may be, for example, from which source the request came, such as a "red cross". The alarm type may indicate audio, display, and/or vibration. The text may be a dialog such as "request further information".
12. The UE responds according to the request using, for example, SMS or http, for example, to provide personnel status, needs and conditions.
13. The UAV receives, stores, and analyzes the received information and takes appropriate action in response to the analyzed data.
The auxiliary sib (aux sib) is a message including an emergency response trigger requesting an automatic response, has information on how to respond, and has what information.
The auxiliary SIB messages may include one or more of the following:
○MessageIdentifier: the source of the field description corresponding to SIB10, e.g., including a bit indicating the required automatic and/or manual response
○AlertType: how the CD should alert the user, without alert, sound, vibration and/or display
○Counter with a memory: 1 to n (temporary counter identifiers to facilitate keeping track of the number of CDs, i.e., acting as message IDs), different paging messages may have different counter values, thereby allowing improved analysis of responses
○Type of trigger: required automatic and/or manual response
○Access information: information enabling CDs to connect to UAVs, such as cell IDs and network IDs included in conventional RACH and/or emergency RACH, to connect without identification
○Response method: indications of possible response protocols for further information, such as SMS, embedded voice call, http, app, text, chat, video, image, audio
○Response address: connecting to a responderLaw-e.g. emergency number or other telephone number for calling, or UR L for receiving information relating to emergency area
○Response data: the data included in the response is required.
The CD receives and decodes the error _ response _ trigger included in the existing SIB10/SIB11 or the auxiliary SIB. The CD sends an autonomous emergency response message, which is included or embedded in the voice call via SMS, http, in or after the RACH procedure, and optionally further after the initial access. Further manual responses may be requested when further data is needed to decide the appropriate action to take with the UAV. In the case of receiving a trigger via SIB10/SIB11, the CD response may include one or more of a CD _ ID, CD _ time, and predetermined data such as location, battery status, biometric data, and acceleration data.
In the case of receiving a trigger via an auxiliary SIB, the CD response may include one or more of a CD _ ID (random temporary ID), a CD _ time, a received counter value n, predetermined data such as location, battery status, biometric data and acceleration data, and further data according to auxiliary SIB field response data, such as:
-input number of nearby persons, and/or
-input health status: 0= good, 1= stress, 2= injury.
The UAV then collects and aggregates data from CDs within range and within time intervals for decision support. The collected data may be:
● determine the number of CDs within the range and within the time interval,
○ known CD (such as a pre-registered CD for rescuers, and other CDs not previously known)
● determining the number of responding CDs
○ known CD (such as a pre-registered CD for rescuers, and other CDs not previously known)
● determining the status of each responding CD
○ aggregate status from responding CDs within range and time interval
● record CD response (e.g., counter, time, UAV, and location of CD)
The number of CDs found, the number of CDs responded to, and the number of CDs within range and providing manual responses within a time interval may, for example, provide a ratio of people who manually responded to/CDs found. A low ratio may indicate that few people are able to respond, i.e., an unclear condition. A high rate may indicate many responses, i.e. a better overview of the situation and possible emergency needs.
The advantage of receiving and aggregating CD responses is to obtain important data from the emergency area and to both identify the person in distress and get an overview of the situation. Through this process, the UAV will know the number of CDs in the area, the number of responding CDs in the area, and the emergency status of individual CDs and CDs within range.
The UAV may continuously analyze the collected data as it collects data from one or more CDs and determine to take appropriate action based on UAV sensor data and UAV states, among other things and where possible. The UAV sensor data may, for example, provide information about the surrounding environment. The UAV state may be, for example, a battery state or a fuel state.
High rates and emergency needs that may be combined with UAV data (audio, images, etc.) may indicate a hazard, further may be combined with available UAV flight times, may indicate that the UAV should be directed back to the operations center immediately.
The UAV may now take appropriate action in accordance with the determined emergency state.
The emergency _ response _ trigger transmitted by the UAV may be included in an existing SIB (SIB 10 or SIB 11) as a predefined value in the SIB field serial _ number. The predetermined value may for example represent "triggering an automatic response: 1 (yes) "or" triggers automatic and manual responses: 0 (NO) ".
The CD receives and decodes the received value, such as, for example, a "trigger automatic response" of the field serial _ number: 1 (yes) ", and automatically responds and includes predefined data such as, for example, location, battery status, CD _ ID, and accelerometer data. Receiving and decoding information such as "trigger automatic and manual responses: a value such as 0 (no) "may additionally allow the user to communicate with the UAV by responding to certain predetermined questions. In the latter scenario, such communication may begin in a conversation, including an appropriate number of interactions, depending on the response.
In order for a CD to respond to an existing SIB, it is required that the CD be programmed to respond in a predetermined manner upon receiving the authentication _ response _ trigger, or that an application installed in the CD be configured to cause the CD to respond in a predetermined manner.
Another alternative is to use a separate secondary SIB to include the emergency _ response _ trigger, which allows more details about the type of response required, such as how to respond, synchronize data, and which data to include.
When a CD receives a secondary SIB (which triggers a response), it decodes the system information and its fields and responds accordingly. This requires programming the CD to respond according to the information included in the auxiliary SIBs.
An advantage of the auxiliary SIB over using SIB10 or SIB11 is a dedicated SIB with fields that can be modified to trigger alternative CD responses. The counter may be used, for example, by the UAV to keep track of the transmitted SIBs (associated with the UAV location and clock) and to map the transmitted SIBs with the CD responses.
The proposed embodiments are beneficial for UAVs simulating emergency situations of cellular networks in areas that are completely uncovered, as well as in disaster conditions like flood, seismic conditions where a large number of people may provide critical information to emergency centers in areas that are partially uncovered.
